  • IPS e.max®

With versatility, reliability and longevity in mind, e.max is unmatched in clinical success. With biocompatible lithium disilicate ingots, e.max offers optimized esthetic properties, creating restorations that offer true-to-natural results. 

The ultimate in metal-free esthetics and durability for both anterior and posterior applications. Provides unmatched strength (400 MPa flexural strength). Indicated for single-unit crowns and 3-unit anterior bridge cases (from 2nd bi-cuspid forward).

Do you know why Etching and Silanization is important for IPS e.max? 

It helps IPS e.max will attached to teeth more properly in a long timeline. Astro Dental Art provides Etching and Silanization service for our clients.

Etching and Silanization

Buffered Hydrofluoric Acid Gel
BISCO’s PORCELAIN ETCHANT improves the adhesive bond between porcelain and cement by increasing the surface area of the porcelain to be bonded. The effect is similar to sandblasting but is more controlled and effective. PORCELAIN ETCHANT will microscopically roughen the feldspathic porcelain or glass surface. BISCO’s PORCELAIN ETCHANT is available in 2 concentrations: 4% or 9.5% (Hydrofluoric Acid Gel).

37% Phosphoric Acid Etchant with Benzalkonium Chloride
Etch-37 w/BAC is a 37% phosphoric acid semi-gel etchant that is effective at quickly etching enamel and dentin. Etch-37 w/BAC is polymer-thickened and effectively removes the smear layer, etches and demineralizes enamel and dentin. It is easily manipulated into small areas such as endodontically treated root canals and undercuts. This makes it more versatile than some thicker gel etchants for etching all restorative surfaces. Published research proves that BISCO etchants produce higher bond strengths to (wet or dry) dentin1 and enamel.

  • Rinses away cleanly and quickly leaving no residue to interfere with bonding
  • Blue in color for easy visualization and contrast
  • Creates microretentive surface characteristics that are necessary for successful bonding.
  • New bulk syringe delivery system availabl
  • Contains benzalkonium chloride (BAC), an antimicrobial agent. In-vitro research shows it is effective against Actinomyces viscosus2.

BIS-SILANE

A two-part Silane coupling agent offering additional shelf-life stability to ensure long lasting effective bonding to porcelain.

 

 

 

 
  • Feldspathic Veneers

Minimal Prep Veneers - Feldspathic veneers have been made popular by patients for their non-invasive preparation requirements, and their ability to allow the existing tooth shades to shine through.

This hand-crafted veneer is created with artistry by use of a brush and glass-based powder mixed with liquid. This material is highly translucent and mimics natural dentition when applied properly. To fabricate feldspathic veneers, the technician hand paints the veneer layer by layer so contour and texture can be controlled and crafted. Then the veneer is baked on a foil tray to solidify. The results are a highly esthetic restoration that is ideal for anterior restorations where shape, texture, and natural-beauty are priorities.

 

  • PFM

PFM combines the strength of a metal coping with hand layered porcelain. The metal base gives off a natural-like hue from within that is complimented when porcelain is applied.

A PFM crown has been known to leave the appearance of a dark line at the gums in some cases, and because of the core being comprised of metal, sometimes the quality of the metal is not up to standard. Thankfully you now have a choice of what type of PFM crown you would like to order. We can use standard metals, noble metals, or high noble metals which are precious alloys. It’s even possible now to combine the benefits of a metal structure with the digital technology of milling the base of the crown in a digital milling machine.
